EURO-DNA-CALC 1.1 released

The current version is 1.1.1 Download it if you obtained previous version (1.1) which had a bug for deCODEme data.

A new version of the EURO-DNA-CALC has been released. The previous version (1.0) was described here.

Version 1.1 also uses deCODEme/23andMe data for an individual but outputs a maximum likelihood estimate of his admixture proportions from the three groups NW European, SE European, and Ashkenazi Jewish.

Below are the admixture estimates for Greg and Lily Mendel of 23andMe. An examination of the confidence intervals output by the program suggests that non-NW European admixture in Greg is a strong possibility, while Lily could conceivably have no non-NW European admixture. On the other hand, Lily's 10% Ashkenazi and only 1% SE European admixture imbalance is interesting. As with all genetic tools, the results should be interpreted in the light of other information about a person's ethnic origin and genealogy.

Dinekes, I've added your tool to the genomics secondary market database. What is your full name so that I may credit you with authorship, or if you would prefer an alias, under what name may I list you?

I`m of african-American with multi-mixtures back ground. I would like to find out my European origin, so would the Euro-calu 1.1 works for some like me with only 19%European and 10% asian DNA ? I`m currently uses DNA Tribes, FamilyTree DNA & 23andMe.If not, could you please point me some web sites where i might recieve such information. Thank you.

I ran my dna file from 23andme thru your calc program.I got:NW Euro 65%SE Euro 15%Ashkenazi 20%My father is from Germany and and far as I know he is not Jewish.My mothers mother is Romanian (both parents from Romania)and my mothers father ancestors have been here for hundreds of years with a little native american and african in the mix (1/2 % each).My question is, is it accurate that I am really 20% Jewish?Thanks!

I didn't notice the intervals only the pie chart. I re ran it and here are the results: "NORTHWEST EURO: Maximum Likelihood Estimate=65% Interval=[38, 89]"[1] "SOUTHEAST EURO: Maximum Likelihood Estimate=15% Interval=[0, 52]"[1] "ASHKENAZI JEWISH: Maximum Likelihood Estimate=20% Interval=[0, 42]"As I said, my father is from Germany and my mother is half Romanian and the other half mostly European from the UK.Can you explain what the Intervals mean? Am I 20% Jewish?Thanks

Is there any way to reverse-engineer the Frankish-Byzantine-Levantine components from one's "Global Similarity" scores in 23andMe? I'm trying to figure out a multiple-regression set up with the use of many people's results.

I'm also African American and no it does not work. It shows me to be 64% Southeast European, 0% Northwest European, and 36% Ash. Jew. LOL This does not at all coincide with 23&me, they say I'm at least 62% African, but likely more because they have serious issues overestimating "Asian" (really Native American) ancestry in New World Blacks.

My Central European girlfriend is shown as having 21% Ash Jew, 40% NW Euro, 39% SE Euro. Based on where she is from and her families name and known time in the area I doubt she has any Jewish ancestry that is in the last 200-300 years anyway...the location of her country makes it typical that she would come out as an even split between NW and SE...so with that it appears accurate and matches up with 23&me fairly well as she is almost equally related to Southern and Northern Europeans.

Those Europeans baffled by indications of Jewish roots should keep in mind that the early church was populated almost exclusively by Jews, who reached out to their pagan Gentile neighbors and included them in the church. Their children, raised in the same faith, naturally intermarried and with each generation the Jewish genes were spread wider, so I would estimate all Europeans have at least some Jewish roots.

The Jews were a small part of the Roman Empire, so even if they were ALL of Jewish origin, and had ALL converted to Christianity, and ALL their genes had spread uniformly across Europe, it would amount to a few % at most, spread evenly across Europe.

I have run two dna files (23andME) through the EuroDNACalc program. I have a new computer with Windows 7 and I can't seem to run a third DNA file on my new computer. Is there a new version for Windows 7 I should use?Thank you.

I tried to use the calculator on my 23andme results and it is giving me an error. Any thoughts as to the cause?> EuroDNACalc("23andme")Error in if (allele1 == "-") { : missing value where TRUE/FALSE needed

I must be really cumputer stupid, but I cant seem to get this to work for me, I removed all of the comment lines from my 23and me file, but cant get past that. I go to change directory and cant find my data file. I changed the data file to a .R file and still no luck, any help would be appreciated
